I think VE tables are not used to tune the Gen-IV motors.

I stand corrected; especially on a 420 stroker.

Check engine light came on last night (200ish miles driven after install) w/ code p1075...air/fuel management. I checked the O2 wires thinking they may have burned on the collectors but, they look fine and have plenty of clearance.

I'm glad I'm not a tuner, there is just too much to keep up with. My '02 OS doesn't even list p1075. There is nothing between p0804 and p1106 in my list.
